Cautions and warnings

General

1. EPCOS metal oxide varistors are designed for specific applications and should not be used

for purposes not identified in our specifications, application notes and data books unless oth-

erwise agreed with EPCOS during the design-in-phase.

2. Ensure suitability of SIOVs through reliability testing during the design-in phase. SIOVs

should be evaluated taking into consideration worst-case conditions.

3. For applications of SIOVs in line-to-ground circuits based on various international and local

standards there are restrictions existing or additional safety measures required.

Storage

1. Store SIOVs only in original packaging. Do not open the package prior to processing.

2. Recommended storage conditions in original packaging:

Storage temperature: ꢀ25 °C ... +45 °C,

Relative humidity:

<75% annual average,

<95% on maximum 30 days a year.

is to be avoided.

Dew precipitation:

3. Avoid contamination of an SIOV's during storage, handling and processing.

4. Avoid storage of SIOVs in harmful environments that can affect the function during long-term

operation (examples given under operation precautions).

5. The SIOV type series should be soldered after shipment from EPCOS within the time speci-

fied:

SIOV-S, -Q, -LS, -B, -SNF

ETFV/ T series, -CU

24 months

12 months.

Handling

1. SIOVs must not be dropped.

2. Components must not be touched with bare hands. Gloves are recommended.

3. Avoid contamination of the surface of SIOV electrodes during handling, be careful of the

sharp edge of SIOV electrodes.

Soldering (where applicable)

1. Use rosin-type flux or non-activated flux.

2. Insufficient preheating may cause ceramic cracks.

3. Rapid cooling by dipping in solvent is not recommended.

4. Complete removal of flux is recommended.

5. Temperatures of all preheat stages and the solder bath must be strictly controlled especially

for T series (T14 and T20).

Please read Cautions and warnings and

Important notes at the end of this document.

HighE, standard, LS50 series

Mounting

1. Potting, sealing or adhesive compounds can produce chemical reactions in the SIOV ceramic

that will degrade the component’s electrical characteristics.

2. Overloading SIOVs may result in ruptured packages and expulsion of hot materials. For this

reason SIOVs should be physically shielded from adjacent components.

Operation

1. Use SIOVs only within the specified temperature operating range.

2. Use SIOVs only within the specified voltage and current ranges.

3. Environmental conditions must not harm SIOVs. Use SIOVs only in normal atmospheric con-

ditions. Avoid use in deoxidizing gases (chlorine gas, hydrogen sulfide gas, ammonia gas,

sulfuric acid gas etc), corrosive agents, humid or salty conditions.Contact with any liquids and

solvents should be prevented.

Display of ordering codes for EPCOS products

The ordering code for one and the same EPCOS product can be represented differently in data

sheets, data books, other publications, on the EPCOS website, or in order-related documents

such as shipping notes, order confirmations and product labels. The varying representations of

the ordering codes are due to different processes employed and do not affect the

specifications of the respective products. Detailed information can be found on the Internet

under www.epcos.com/orderingcodes

Important notes

The following applies to all products named in this publication:

1. Some parts of this publication contain statements about the suitability of our products for

certain areas of application. These statements are based on our knowledge of typical

requirements that are often placed on our products in the areas of application concerned. We

nevertheless expressly point out that such statements cannot be regarded as binding

statements about the suitability of our products for a particular customer application. As a

rule we are either unfamiliar with individual customer applications or less familiar with them than

the customers themselves. For these reasons, it is always ultimately incumbent on the customer

to check and decide whether a product with the properties described in the product specification is

suitable for use in a particular customer application.

2. We also point out that in individual cases, a malfunction of electronic components or failure

before the end of their usual service life cannot be completely ruled out in the current state

of the art, even if they are operated as specified. In customer applications requiring a very high

level of operational safety and especially in customer applications in which the malfunction or

failure of an electronic component could endanger human life or health (e.g. in accident

prevention or life-saving systems), it must therefore be ensured by means of suitable design of the

customer application or other action taken by the customer (e.g. installation of protective circuitry

or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or

failure of an electronic component.

3. The warnings, cautions and product-specific notes must be observed.

4. In order to satisfy certain technical requirements, some of the products described in this

publication may contain substances subject to restrictions in certain jurisdictions (e.g.

because they are classed as hazardous). Useful information on this will be found in our Material

Data Sheets on the Internet (www.tdk-electronics.tdk.com/material). Should you have any more

detailed questions, please contact our sales offices.

5. We constantly strive to improve our products. Consequently, the products described in this

publication may change from time to time. The same is true of the corresponding product

specifications. Please check therefore to what extent product descriptions and specifications

contained in this publication are still applicable before or when you place an order.

We also reserve the right to discontinue production and delivery of products. Consequently,

we cannot guarantee that all products named in this publication will always be available.

The aforementioned does not apply in the case of individual agreements deviating from the

foregoing for customer-specific products.

6. Unless otherwise agreed in individual contracts, all orders are subject to our General Terms

and Conditions of Supply.

7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard.

The IATF certifications confirm our compliance with requirements regarding the quality

management system in the automotive industry. Referring to customer requirements and

customer specific requirements (“CSR”) TDK always has and will continue to have the policy of

respecting individual agreements. Even if IATF 16949 may appear to support the acceptance of

unilateral requirements, we hereby like to emphasize that only requirements mutually agreed

upon can and will be implemented in our Quality Management System. For clarification

purposes we like to point out that obligations from IATF 16949 shall only become legally binding if

individually agreed upon.
